Hey my friends! My daughter and I own a '99 Mustang GT 4.6 V8 with 104,000 miles. Its been a great machine. Last year the car started to develop a problem. It would crank over with no start. No Check Engine light. Come back and it would start and run fine for a few days. Last fall as we were putting her up for the winter months, it was running fine. we finished cleaning her up and when to put in machine shed and it would not start....4 days later it starts. Parked it.
Fast forward to April and we try to start it, battery weak so we jump it but it would not fire. Installed new battery, nothing. I start researching problems and asked questions. I bought scanner and it pulled a pending code PO 191 FRPS. We replaced it, cranked but no start. cranked again and it fired up!! Woohoo problem solved so I thought. The car ran for 6-7 minutes and just died. I was told fuel pump is problem. I listened and heard fuel pump kick on when key was turned on. So I did a test of spraying some start fluid in my intake and car fired till SF wore off. I do not have a fuel pressure test gauge, I did have pressure when I replaced the Fuel Rail Pressure Sensor so I think fuel pump is good? I have not replaced the fuel pump yet. I also noticed the Tach did not move during cranking over, but would work when car did start. Cam position sensor? I was also told to have Alt checked for proper Amps? Any truth to that? Please if you can shed some light on places to look our check, I would greatly appreciate it. Thank you so much my friends...
